FASTENING FOR PLATE-GLASS AND SHOW-GASES.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed March 18, 1907. Serial No.'363.l40.

To all whom it may concern:

Be it known that I, CHARLES M. OoNLEY, a citizen of the United StatesofAmerica, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Fasteningsfor Plate-Glass and Show-Cases; and I hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and usethe same.

This invention relates to improvements in fastenings for plate glass andshow cases.

The object of this invention is to provide a clamp for securing glassplates together which will have few parts, which can be readilyassembled and which can be placed in position without the exercise ofany high degree of skill.

With this object in view and to the end of realizing other advantagesthat will hereinafter appear this invention consists in certaincombinations and arrangement of parts as described in the specification,illus trated in the drawings and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front view of a portion oftwo plates of glass secured together by a clamp embodying my invention.Fig. 2 is a section on line 22, Fig. 1. Fig. 3 is a section on line 33,Fig. 1. Fig. 4 is a rear View similar to Fig. 1. Fig. 5'shows the twomembers of the clamp detached.

Again referring to the drawings 1 and 2 represent two plates of glasswhich are arranged at an angle to each other. Between the meeting edgesof the glass plates is preferably arranged a filling 3 of cloth, cementor other suitbale material. The clamp comprises an outer memberconsisting of an angle plate 4 which is provided with a flat stem 5which extends between the edges of the abutting glass plates. The stem 5is made a suitable length so that it will project beyond the inner facesof the glass plates. The stem 5 may be formed integral with the angleplate 4 or may be secured thereto in any suitable manner. In the stem 5near its outer end is formed an inclined slot 6 which extends from apoint near the center of the stem rearwardly towards the free end of thestem. A small projection 7 is located on the inner face of the outerclamp member at each side of the stem 5 and the glass plates at thepoint where the clamp is to be fastened are slightly notched at theirouter edges so as to receive these projections. The inner member of theclamp comprises an angle plate 8 arranged to fit into or correspond tothe inner angle formed by the glass plates 1 and 2. In the angle plate 8is formed a slot 9 which extends upwardly from the lower edge of theangle plate at its center and has a width greater than the thickness ofthe stem 5 so that the angle plate 8 can be slipped down over and reston said stem. On the inner face of the angle plate 8, around the slot 9,is formed a reinforcing flange 10. The locking member consists of ayoke-,

shaped cam device 12 which is arranged to straddle the stem 5 and isrotatably mounted thereon by means of a pin 13 which passes through theslot 6.

When assembling a show-case, show-window or similar construction, withthe use of my clamps, the glass plates are arranged at the desired anglewith their edges abutting and the outer edge of each plate is slightlynotched at the point where the clamp is to be secured. The outer clampmember is then placed in its proper position and the stem 5 is passedbetween the edges of the glass plates. The inner clamp member 8 is thenslipped down on the stem 5 where it projects beyond the inner faces ofthe plates and the locking member is mounted on the inner end of thestem by inserting the pin in the slot 6 and the locking member is thenswung around so as to bring the cam face thereof in contact with thereinforcing flange 10 on the inner clamp member.

My clamp, while combining all the practical features of clamps of thischaracter now in the market, is particularly valuable because it can beassembled, by a person having little or no skill, without danger ofbreaking the plates. Heretofore great loss has been caused by thebreaking of the glass plates through the misjudgment or over zeal on thepart of the workmen in attempting to clamp the plates too tightlytogether. With my clamp when the thickness of the glass is known the Ilength of the slot 6 in the stem 5 can be adjusted and the curvature ofthe cam face on the locking member can be calculated so as to secure theproper pressure and therefore nothing is left to the judgment of theworkmen,

What I claim is:

1. In a construction of the character indicated the combination with twoplates arranged at an angle to each other of an outer clamping member, astem extending from said outer clamping member and passing between theabutting edges of said plates and projecting beyond the inner facesthereof, an inner clamping member arranged to fit the angle formed bythe inner faces of said plates and a cam shaped locking member rotatablymounted on the said stem so as to swing in a plane parallel with saidstem and arranged to come in contact with the inner mem her so as toclamp the glass between the inner member and outer member of said clamp.

2. In a construction of the character indicated the combination with twoglass plates arranged at an angle to each other of an outer clampingmember, a stem extending from said outer member between the abuttingedges of said plates, an' inner clamping member arranged to straddlesaid stem, a reinforcing flange arranged on the inner face of said innermember and a cam device mounted on the inner end of said stem andarranged to come in contact with the reinforcing flange on the innermember so as to clamp the plates between the inner and outer members ofthe clamp.

3. In a construction of the character indicated the combination with twoplates arranged at an angle to each other of an outer clamping member, astem extending from the outer member between the abutting edges of theglass plates, an inner clamping member having a II-shaped groove ofsuflicient width to receive said stem a reinforcing flange formed aroundthe groove in said inner member I and a cam shaped locking memberpivotally supported on said stem and arranged to come in contact withthe flange on the inner clamp member so as to clamp the glass betweenthe inner and outer clamp members.

4. In a construction of the character indicated the combination with twoglass plates arranged at an angle to each other of an outer clampmember, a stem extending from said outer clamp member between theabutting edges of the glass plates, said stem being provided with arearwardly inclined slot, an inner clamping member, a camshaped lockingmember, a pin extending through said locking member and the slot in saidstem and the arrangement is such that when the locking member is in itsoperative position it will clamp the glass plates between the inner andouter members of the clamp.

5. In a device of the character indicated the combination with two glassplates arranged at an angle to each other of an outer angle plate, astem extending from said angle plate between the abutting edges of theglass plates and provided with a slot, an inner angle plate having aU-shaped slot at its center of sufficient width to receive said stem andprovided with a reinforcing flange around said slot, a cam-shapedlocking device arranged to straddle the end of said stem, a pinextending through said locking device and the slot in said stem, and-thearrangement is such that when the locking device is in its operativeposition it will cause the inner and outer members to tightly engage theglass plates.

6. In a device of the character indicated, the combination with twoglass plates having notches in their outer edges and arranged at anangle to each other of an outer angle plate, a stem extending from saidangle plate between the abutting edges of the glass plates and providedwith a slot, a projection arranged on the inner face of said outer angleplate at each side of the said stem, an irmer angle plate having aU-shaped slot at its center of suflicient width to receive said stem andprovided with a reinforcing flange around said slot, a cam-shapedlocking device arranged to straddle said stem, a pin extending throughsaid locking device and the slot in said stem and the arrangement issuch that when the locking device is in its operative position it willcause the clamp members to tightly engage the glass plates.

In testimony whereof, I sign the foregoing specification, in thepresence of two witnesses.
